Bergenia plant named ‘Spring Fling’

ABSTRACT

A new and distinct  Bergenia  plant characterized by numerous inflorescences flowering at about the same height, large, deep pink flowers, clean, shiny and dark red brown winter leaves, and excellent vigor.

Botanical denomination: Bergenia hybrid.

Variety designation: ‘Spring Fling’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bergenia hybrid and given the cultivar name of ‘Spring Fling’. Bergenia is in the family Saxifragaceae. The new cultivar originated from a planned breeding program to create outstanding garden Bergenia. The new cultivar was created from controlled crosses using proprietary parents. The exact parents were not recorded and are unknown.

SUMMARY OF THE INVENTION

This new Bergenia is unique in having:

-   -   1. numerous inflorescences flowering at about the same height,     -   2. large, deep pink flowers,     -   3. clean, shiny and dark red brown winter leaves, and     -   4. excellent vigor.

Compared to Bergenia ‘Bressingham Ruby’, U.S. Plant Pat. No. 7,344, the new cultivar has larger flowers, smaller leaves, more crowns and more flowering stems with shorter flower stalks.

Compared to Bergenia ‘Rotblum’, an unpatented plant, has larger flowers, smaller leaves, more crowns and more flowering stems that are more upright.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by tissue culture using standard micropropagation techniques with terminal shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may change with variations in environment without a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Bergenia based on observations of nine-month-old specimens grown in the ground in full sun in the trial fields in late April in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95 degrees F. in August to an average of 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart, 5^(th) edition.
